As the post notes,
“In September 2007 I was hired jointly by Transvideo Studios and Google, both headquartered in Mountain View California. Transvideo had a contract with Google and took care of 100% of their video production in Mountain View, and sometimes elsewhere. My labor was sold to Google in the form of a 9-5 job. I had access to a personally unprecedented amount of privileges, but was not entitled to the ski trips, DisneyLand adventures, stock options, and holiday cash bonuses from their team of temporary Santa Clauses. Thousands of people with red badges (such as me, my team, and most other contractors) worked amongst thousands of people with white badges (as Full-time Googlers). Interns are given green badges. However, a fourth class exists at Google that involves strictly data-entry labor, or more appropriately, the labor of digitizing. These workers are identifiable by their yellow badges, and they go by the team name ScanOps. They scan books, page by page, for Google Book Search. The workers wearing yellow badges are not allowed any of the privileges that I was allowed – ride the Google bikes, take the Google luxury limo shuttles home, eat free gourmet Google meals, attend Authors@Google talks and receive free, signed copies of the author’s books, or set foot anywhere else on campus except for the building they work in. They also are not given backpacks, mobile devices, thumb drives, or any chance for social interaction with any other Google employees. Most Google employees don’t know about the yellow badge class. Their building, 3.14159~, was next to mine, and I used to see them leave everyday at precisely 2:15 PM, like a bell just rang, telling the workers to leave the factory. Their shift starts at 4 am.”
And read the rest of the post to see what happened when he tried to meet the Epsilons of that system.
